Hi all,
I currently run my house on 48v battery system (lead acid) and recently got hold of a damaged Tesla PW2. I have repaired the PW2 and modified it to be a 13s config rather than the original 12s it came out the factory with. Its inverter has been completely removed so because of that its essentially just a 13s Li-ion big battery and does not operate in same way a normal Powerwall would.
I don't want to change out the working lead acid batteries as nothing wrong with them but I also don't want to let PW2 be un-used.
What I was thinking was thinking was to combine the 2 systems like I have drawn in my very rough diagram-
So I want to combine the output of the 2 different batteries but due to different charge capabilities they will each have their own charge system that wont effect each other due to power only being allowed to flow in 1 direction from PW2 into the line that is then fed into inverter before being converted to supply house.
Obviously they would need to be at the same voltage when connecting them together so thats why the PW2 has been increased to be able to be at higher voltage to come closer inline to where the lead acid ones want to be operating.
Will this actually work and be useable like this or is there something I'm missing?
I realize this probly isn't something that lots of ppl have setup so anyone who may have some insight and more knowledge on power systems in general would much appreciate your input.
Thanks
